Abstract:

Carbon dioxide is a kind of gas that can be produced by the human body. It is non-toxic and harmless, and plays an important role in the physiological function of the human body. Carbon dioxide has been widely used to improve physical health in recent years. Carbonated skin care products are a kind of skin care products containing carbon dioxide or producing carbon dioxide during the process of use, and they have become one of the hot products in the skin care industry. Carbon dioxide present in the products or produced in use of the products can enter the skin and cause the Bohr effect and thus achieve the purpose of skin care. In the market of skin care products, the safety and efficacy of carbonated skin care products are gradually recognized and accepted by domestic consumers. However, most consumers know little about their working mechanism. In this paper, a commercially available carbonated skin care product was studied to explore the conditioning effects on women’s skin. The VISIA-CR skin detector and the Moisture Meter SC were used to study the effects of the carbonated skin care product on blood circulation, pores and absorption. The deep cleansing effect of carbonated skin care products was also discussed. The results show that carbonated skin care products can improve the local skin microcirculation and promote pore expansion, which provides conditions for the subsequent absorption of effective ingredients in the skin care products. Moreover, the pore expansion caused by carbonated skin care products is conducive to removing blackhead and deep skin cleansing. However, the improvement of local blood circulation and the pore expansion are temporary, that is, blood circulation will gradually weaken with time and finally return to normal level, and the pore size will gradually recover and even pore contraction phenomenon appears. Carbonated skin care products are expected to fundamentally solve basic skin problems by accelerating skin blood circulation, promoting the absorption of effective ingredients and effectively removing deep waste in the skin.

Key words: carbonated skin care product, Bohr effect, blood circulation, pore expansion, absorption promotion, deep cleansing
